Study on Mechanism of Dahuang Huanglian Xiexintang in Treatment of Type 2 Diabetes Mellitus Based on Network Pharmacology / 中国实验方剂学杂志

ABSTRACT

Objective: To explore the mechanism of Dahuang Huanglian Xiexintang in the treatment of type 2 diabetes mellitus based on network pharmacology. Method: Major chemical constituents, corresponding targets and target genes of Dahuang Huanglian Xiexintang were obtained by Traditional Chinese Medicine Systems Pharmacology(TCMSP), and target genes of type 2 diabetes mellitus were obtained by GeneCards. The target genes of drug and disease were mapped to predict target genes of Dahuang Huanglian Xiexintang for type 2 diabetes mellitus. Cytoscape3.7.1 software was used to construct the compound-target network and protein-protein interaction network (PPI) of traditional Chinese medicine. Gene ontology (GO) analysis of potential genes and enrichment analysis of gene encyclopedia kyoto encyclopedia of genes and genomes (KEGG) pathway were carried out using DAVID 6.8 online tool. Result: There were 17 active ingredients, 94 related targets, 17 key active ingredients and 16 key targets in Dahuang Huanglian Xiexintang on type 2 diabetes mellitus. GO analysis showed that the biological functions of potential genes of Dahuang Huanglian Xiexintang in the treatment of type 2 diabetes were mainly related to oxidative stress, apoptosis, protein binding, inflammatory reaction, et al. KEGG pathway enrichment results showed that the pathways of potential genes of Dahuang Huanglian Xiexintang in the treatment of type 2 diabetes mainly involved hypoxia inducible factor(HIF), tumor necrosis factor(TNF), phosphatidylinositol 3 kinase/protein kinase B(PI3K/Akt), nuclear transcription factor-кB(NF-кB), and vascular endothelial growth factor(VEGF) signaling pathways. Conclusion: Dahuang Huanglian Xiexintang is a complex process of multi-component, multi-target and multi-pathway in the treatment of type 2 diabetes mellitus. It plays an important role in the treatment of type 2 diabetes mellitus by participating in oxidative stress, apoptosis, protein binding and inflammatory reaction.
